A portion of the disclosure of this patent documentcontains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files orrecords, but otherwise reserves all copyrights whatsoever.TECHNICAL FIELDThis invention relates generally to a computer system for transmitting data on a computer network, and more specifically, to a method and system for transmitting data in raw mode.BACKGROUND OF THE INVENTIONLocal Area Networks (LANs) are very popular means for interconnecting computers, especially personal computers. These computers are interconnected, in part, so that data may be electronically transferred from one computer to another and so thatusers can share resources such as files.Several different type computers and computer operating systems can exist on a given network. For example, some of the computers can run Microsoft's OS/2 operating system and other computers can run a Unix-based operating system. Thesedifferent computer systems need to transfer information in a protocol. The use of protocols in diverse computer systems is somewhat analogous to the use of the transmission protocols of AM and FM radio. An AM radio can only receive AM protocol signals,an FM radio can only receive FM protocol signals. Similarly, diverse computer systems cannot communicate unless they use the same protocol.One such protocol for computer system file sharing is defined in the document entitled "Microsoft Networks/OpenNET FILE SHARING PROTOCOL," which is available from Intel Corporation as Intel Part Number 138446, and is hereby incorporated byreference. Systems that use that protocol can obtain or provide remote file services in a network environment. This protocol is referred to as the System Message Block (SMB) protocol because the protocol defines how data is to be packaged with SMBheaders to be t
